HYMATIC HY-802HDT 25L 35cc 4-Stroke High Pressure Double Suction Power Sprayer

The HYMATIC HY-802HDT is a heavy-duty 25-litre petrol-operated backpack power sprayer equipped with a fuel-efficient 35cc-type 4-stroke engine and high-pressure double suction brass pump.

Designed for agricultural spraying, orchards, plantations and professional pest-control applications, it delivers consistent spray pressure with reduced vibration, lower fuel consumption and no requirement to mix petrol with engine oil.

Powerful 4-Stroke Performance for Professional Spraying

The HYMATIC HY-802HDT is engineered for farmers and professional users who require high pressure, extended working capacity and reliable field performance.

Its 35cc-type 4-stroke petrol engine provides smooth and efficient operation while eliminating the inconvenience of preparing a petrol and oil mixture. The engine is paired with a horizontal-driven brass pump with double suction technology for stable pressure and uniform chemical delivery.

The large 25-litre chemical tank reduces frequent refilling and makes the sprayer suitable for orchards, plantations, vegetable farms, nurseries and large agricultural fields.

Multiple spray guns and nozzle attachments are supplied with the machine, allowing the operator to adjust the spray pattern according to the crop, application area and required spraying distance.
